Description
Kang An and co-authors check whether a widened upper aorta makes catheter-based valve replacement riskier. Their 2023 study reviews 467 patients who received a new aortic valve through a leg artery between 2016 and 2021. One hundred of them had an ascending aorta at least forty-five millimeters wide, the size that triggers extra surgery in open operations.
Hospital deaths were rare, and no patient suffered injury to the aorta during the procedure. Over follow-up of roughly two years, survival did not differ between the wide-aorta group and the rest. Aorta tears were almost unheard of, with single cases in the narrower group. The authors conclude the catheter route is safe for these patients.
